Looks like Twitter is going to start pushing their “Promoted Tweets” on their mobile apps:

Just like the Promoted Tweets that Twitter shows on its primary Twitter.com site, these ads will show up in users’ “timelines.” At first, Twitter will only allow advertisers to place the ads in front of users who are already following their accounts. But within months, it will expand the program to allow marketers to reach people who don’t follow them — just as it does on the Web.

The big question is if third-party apps will be forced to show these, too, especially since the not-yet-updated version of the regular Twitter iPad app won’t show them (yet):

…One odd exception to the expansion — for now, the ads still won’t show up on iPads…
